If I could rate this episode 6 stars, I absolutely would. Not only is it the most mind-blowing episode of the series in my opinion, but it's one of the most mind-blowing moments I have ever witnessed in any anime period. Such a deep and emotional rollercoaster of a journey that it's hard to describe it in words. It left me completely speechless from beginning to end. All I can say is, the final episode is peak, and even saying that doesn't do it justice. As for the whole series itself, it was an amazing ride overall. There were a few parts in there that felt a bit rushed, but I'm satisfied with all of the stories. All in all, an unforgettable experience!
